Step-in side-clamp safety ski release system

In a ski binding having a housing, a clamping member movably mounted on said housing at one side thereof for lateral movement relative to said housing between a clamp-open position and a clamp-closed position and means for applying a clamping force to said clamping member for releasably securing a ski boot to a ski rearward of the toe and forward of the rear of the heel of the ski boot, an improvement for opening and closing said clamping member comprising:

• a lever member of one-piece construction spaced from and independent of said clamping member, said lever member having a first and a second end and being movable about an axis therethrough intermediate said ends from a clamp-open to a clamp-closed position and return, said lever member being movable to its clamp-open position against said clamping force in response to a force applied to said first end thereof to permit movement of said clamping member to its open position;
• and
• means for holding said lever member in its open position against said clamping force when the force applied to said first end of said lever member is removed therefrom, including a surface means on said lever member for engaging a facing surface on said housing in a manner to cause said lever member to be restrained from moving relative to said housing until the force is applied to said lever member to move it to its clamp-closed position;
• said lever member being movable to its clamp-closed position in response to downwardly applied pressure brought to bear on said second end thereof to permit release of said lever member from said holding means when said ski boot is in skiing position and to allow said clamping member to move to said clamp-closed position under the influence of said clamping force.

In a ski binding having a housing, a clamping member movably mounted in said housing for movement relative to said housing between a clamp-open position and a clamp-closed position and means for applying a clamping force to said clamping member for releasably securing a ski boot to a ski rearward of the toe and forward of the rear of the heel of the ski boot, an improvement for opening and closing said clamping member comprising:

• a connecting member for engaging said clamping member;
• a lever member spaced from and independent of said clamping member having a first and a second end movable about an axis intermediate said ends between a clamp-open and a clamp-closed position;
• means for movably connecting said lever member to said connecting member;
• means depending from said lever member for slidably engaging in said housing and for moving said lever member and said connecting member relative thereto against said clamping force in a first direction in response to a force applied to said first end thereof to allow said clamping member to move to its open position;
• means for holding said lever member in its open position against said clamping force when the force applied to said first end of said lever member is removed therefrom;
• and
• means for moving said lever member out of contact with said housing in a second direction to its clamp-closed position in response to applied pressure brought to bear on said second end thereof for releasing said lever member from said holding means when said ski boot is in skiing position to allow said clamping member to close with said clamping force.

In a ski binding having a housing, a clamping member movably mounted in said housing for movement relative to said housing between a clamp-open position and a clamp-closed position and means for applying a clamping force to said clamping member for releasably securing a ski boot to a ski rearward of the toe and forward of the rear of the heel of the ski boot, an improvement for opening and closing said clamping member comprising:

• a lever member spaced form and independent of said clamping member having a first and a second end movable about an axis intermediate said ends between a clamp-open and a clamp-closed position, said lever member being coupled to said clamping force applying means;
• means for moving said lever member to its clamp-open position against said clamping force in response to a force applied to said first end thereof to allow said clamping member to move to its open position;
• means for holding said lever member in its open position against said clamping force when the force applied to said first end of said lever member is removed therefrom;
• means for moving said lever member to its clamp-closed position in response to applied pressure brought to bear on said second end thereof for releasing said lever member from said holding means when said ski boot is in skiing position to allow said clamping member to close with said clamping force;
• and a pair of heel-step members at the rear of the housing for supporting the heel of a boot and for preventing engagement of said ski boot by said lever member as said clamping member starts to move to its open position.

In a ski binding having a housing, a clamping member movably mounted on said housing at one side thereof for lateral movement relative to said housing between a clamp-open position and a clamp-closed position and means for applying a clamping force to said clamping member for releasably securing a ski boot to a ski rearward of the toe and forward of the rear of the heel of the ski boot, an improvement for opening and closing said clamping member comprising:

• a lever member spaced from and independent of said clamping member, said lever member having a first and a second end and being movable about an axis therethrough intermediate said ends from a clamp-open and a clamp-closed position and return, said lever member being movable to its clamp-open position against said clamping force in response to a force applied to said first end thereof to permit movement of said clamping member to its open position;
• and
• means for holding said lever member in its open position against said clamping force when the force applied to said first end of said lever member is removed therefrom, said lever member being movable to its clamp-closed position in response to downwardly applied pressure brought to bear on said second end thereof to permit release of said lever member from said holding means when said ski boot is in skiing position and to allow said clamping member to move to said clamp-closed position under the influence of said clamping force;
• and a pair of heel-step members on the rear of the housing providing a clearance between the heel of said ski boot and the ski for preventing engagement of said ski boot by said lever member as said clamping member starts to be moved to its open position.
